The project involved a total refurbishment and remodelling of an existing residential structure, focusing on enhancing both aesthetic appeal and structural integrity. A significant feature of this refurbishment was the design and implementation of a rear extension, which included a seamless glass roof light and a green roof system. This refurbishment project successfully integrated advanced structural engineering principles with innovative architectural design. The seamless glass roof light and green roof system not only enhance the aesthetic and functional aspects of the house but also contribute to sustainable building practices. The structural design of the steel beams ensures long-term performance and safety, supporting the unique features of the project
